Textbook Overview

Common Sense Police Supervision is one of Chief Gerald Garner's most established contributions to first-line law enforcement leadership. Now in its seventh edition, the book combines practical experience, supervisory judgment, and specific guidance on the responsibilities routinely encountered by Sergeants and other frontline leaders.

The central philosophy is contained in the title. Effective supervision requires policies, training, professional knowledge, and organizational authority—but it also requires judgment, prudence, perspective, and the ability to apply those resources intelligently to real people and real problems.

The seventh edition addresses:

• training

• counseling

• inspection

• discipline

• performance assessment

• planning

• problem resolution

• communication

• media relations

• complaints

• community policing

• customer service

• career development

• and leading employees from different generations.

Unlike a theoretical leadership text, Common Sense Police Supervision consistently brings the reader back to the practical question:

What should a good first-line leader actually do? That characteristic helps explain its longevity.

Preparation for Oral Boards and Assessment Centers is part of the draw of this textbook. Understanding and citing the specific leadership principles that define why a supervisory action is taking place, or should take place, is the essence of the oral board, in-basket assessment, role-play exercise and many other modern assessment exercises. Quoting directly from the text shows the ultimate in professional preparation for your new role as a supervisor and leader.

Why This Book Matters

The book matters because police supervision rarely occurs under ideal circumstances.

Why we love this textbook and write promotional exams from it: Supervisors deal with incomplete information, difficult employees, competing demands, emotional situations, organizational pressure, citizen concerns, and decisions that cannot always wait for lengthy analysis. Garner's approach emphasizes sound judgment applied to those realities.

The text is therefore useful not merely as a source of promotional-examination information but as a bridge between knowing supervisory principles and applying them.

That makes the book potentially valuable for written examinations, but also equally valuable for In-Baskets, Role Plays, Situational Judgment Tests, and other exercises requiring candidates to demonstrate how they would actually respond to supervisory problems. 

 

Historical Promotional Influence

The book's continued progression through seven editions provides additional evidence of its durability as a police supervision resource. The fourth edition appeared in 2008, a sixth edition in 2018, and the current seventh edition in 2024.

Even more significantly, Charles C Thomas now publishes a seventh-edition companion study guide explicitly designed to reinforce the book's content and assist promotional students preparing for examinations based upon it.

Current Professional Relevance

The seventh edition's 2024 publication makes this a genuinely current supervision text rather than simply an older classic remaining in circulation.

The current edition specifically recognizes a changing workforce and increasingly complex society while retaining practical instruction in discipline, counseling, communication, complaints, performance evaluation, community policing, and leadership. It also addresses leading different generations within the workforce.

That combination is important.

The enduring responsibilities of Sergeants have not disappeared; they have become more complicated. Employees still require leadership, evaluation, counseling, correction, communication, and development. What has changed is the organizational and social environment in which supervisors perform those duties.

This seventh edition attempts to preserve the practical strengths of the earlier editions while adapting them to that environment.

 

If This is the Only Leadership Book You Read ...

If Common Sense Police Supervision is the only supervision book you read, you should emerge with a strong practical understanding of the everyday responsibilities of a first-line law enforcement leader.

You will encounter leadership not as an abstract concept but through activities supervisors actually perform: communicating, counseling, evaluating, disciplining, resolving problems, handling complaints, working with the community, developing employees, and preparing themselves for greater responsibility.

The book will not replace agency policy, legal training, or a comprehensive management education. Nor should "common sense" be interpreted as a substitute for professional knowledge.

Its central contribution is different: professional knowledge becomes most useful when a supervisor has the judgment to apply it effectively.

For officers preparing to become Sergeants—and particularly for candidates who want preparation that extends beyond memorizing information for a written examination—that remains a compelling proposition.
